You can do this in Bash already (Ctrl x Ctrl e is bound to readline's edit-and-execute-command, which will open $EDITOR with the current command), but being able to do this everywh…

The only thing this page is missing is a marquee element :-)

The Thinkpad X1 Carbon or the T470p (which has a Quad i7 and supports upto 32GB of RAM).

Here's another interesting story from the DOS days: https://blogs.msdn.microsoft.com/larryosterman/2004/11/08/ho...

This has nothing to do with memory. The x86_64 ABI returns values from functions in the RAX register.

The CLR uses a similar technique to take over control of execution of a managed EXE - http://srevas.net/notes/2007/12/25/mscoree/

Slightly tangential, and while I know nothing about the implementation details of the SQLPAL, the SSCLI (and later CLR/CoreCLR) took the same approach to port Windows based code to…

You can also launch the TUI after-the-fact using the key sequence 'C-x o'. (It is no accident that it is the key sequence bound to other-window by default in Emacs).

For the 16 byte (on x86_64) header (markOop, klass *).

I think this post misses the point. Having to enter the runtime in the first place is the problem (and making runtime code marginally faster is not the solution). Fast VMs for dyna…

You're missing the point. The original question (and hence my answer) isn't about whether or not it is a good idea to use finalizers. I'm merely pointing out that both in the case …

It might be, depending on exactly what you'd like to implement. There are two things at play here: 1. The memory that holds the resource. 2. The resource itself. C++ RAII lets you …

While I agree that it'd be unusual for regular applications to have to resort to using SEGVs to implement features, low level systems code, especially VMs often do, for performance…

Not necessarily. As long as it wasn't related to the JIT or the GC, one could always look up the SSCLI (ROTOR) code to understand how something was implemented. https://en.wikipedi…

LGDT is an instruction that Loads the Global Descriptor Table [1]. The CPU doesn't know about the persistence of local state in that it doesn't know (in this case), the significanc…

It generally doesn't matter how the machine code came to be. It is theoretically possible to write an operating system for (say) x86 in (say) Javascript. The reason people generall…

There's also a DAW called Reason: https://en.wikipedia.org/wiki/Reason_%28software%29

C++ exception handling is implemented using SEH (so is CLR's IIRC, and Chakra's). SEH is implemented by the OS and is available to non-C++ code too (including C).

While RtlInstallFunctionTable callback was designed specifically for JIT compilers, RtlAddFunctionTable may also be used. The trick is to give every function its own function table…

GNU/kWindows doesn't make any sense to begin with. Modern Windows OS is the NT kernel with the Windows user land. A more appropriate name would be GNU/NT.

Microsoft's research OS was called Singularity [1] and the C# compiler (that compiled to native code) Bartok [2]. [1] http://research.microsoft.com/en-us/projects/singularity/ [2] …
